The Pacific tree frog (Pseudacris regilla), also known as the Pacific chorus frog, is the most common frog in the United States. Their geographical range extends from the west coast of the United States all the way up to Canada. They live in a variety of habitats including seas, deserts and ponds and reproduce in aquatic environments. They have the ability to change colors from brown to green and range from 2 to 2 ½ inches long (ADW 2013) .
They also have unique and specific markings on them such as dark and spotty marks along their sides and on their back, as well as a long black strip that stretches across the eyes and down to the shoulders. Along with their different colors, the Pacific tree frogs have very distinct round and sticky toe pads that differ from other frogs (Breakthrough 2013) .
